E is themetal shank) of a recessed block F,-

which is formedto receive and hold the globe to be glazed, (indicated by 71.) In the em-' bodiment shown there are 'four arms to. the spider, and hencefour of these heads F, one

of which carries the globe whose holes 5 are e, which. are beneaththe holders, whose globes are operated on by the burners G and.

H, are a pair of pinionsJ and J, which are continuously rotated by means of a belt (not shown) passing around pulleys j and 7" on the lower ends of their shafts, which are mounted in frame-.bracketsA By this means whenever a globe comes into juxtaposition with the flame from the burner H or the burner G .the 'globeis. given a tendency to rotate by reason of the pinion e" engaging the continu ously-rotatingpinion J or J4. The frictional en agement between the head F and the tu bu ar' shaft E of the 'inion e is sufficient to normally rotate the ead. Y

The rotation is uninterruptedfront of the burner H to allow the flame from that burnerto gradually-heat the lobe adjacent to theholes z therein. In t e position in front of theflame from the burner G, which is the glazing position, the operator grasps sufficiently to prevent its iota- 1 the head F tion, and. thus holds the globe withthe center ofa hole in the vertical plane of the axis of the flame.' the treadle already referred to, he raises or- 51 bring the f ing theheadby'liand and raislng and lower globe is-held inglth'e head bythe .treadle the with the hole accurately .iniposition.

To hold the spider in position with one of th'e'g'lobe's" acted on by the burner H and the ;-.o the r; -iby the burner G, I provide a latch whichisadapted to engage eac was as it comes into one of the definite positions. This latch is located to cooperate directly with the spider-arm which carries the globe which is acted on by the lazingflame. Thislatch consists of a bar K, s idably mounted in aifl bracket A and havingat its forpair of jaws k and 7c, adapted to n them a lug 1), formed on the he sleeve 1) at the end of each e jaw is is ri id with the bar bell-crank k with a link 7c, which may be operated by a suitable treadle, (not shown,) a spring is tendin to hold the latch in engage- 'ment. When tie treadle is operated, the

link k is drawn downward and the jaws release the'lug 12, allowing the frame B to be turned by hand to bring new globes into position.

I claim- 1. The combination of a rotatable support,

lobe-holders carried, thereby, a heating-.

urner adapted to d ect the flame against one of the globes, a g azing-burner adapted to direct a flame which comes substantlally to a point against another of said globes, and means for adjusting such latter globe with reference to the flame whereby the flame will be caused to pass centrally through a hole in the globe.

' 2. The combination of a rotatable support,

' globe-holders carried thereby, a burner adapted to direct a glazing-flame which comes substantially to a point into an opening in a globe, means for frictionally driving the globe-holder in such position, and means for simultaneously raising or lowering such globe-holder to center the hole with reference to the flame.

3. The combination of a central standard, a-support rotatably mounted thereon, a gas- La r-lifter a 7c is loose, eing held by a rod k secured thereto and the bar K is connecte by a a burner, means for cond gas and air thereto which extend up.

. id through said standard, globe-holders carried by said su port, whereby successive globes are broug t into cooperation with the flame from said burner, each globe-holder being individually rotatable'on its own axis. a

4. The combination of a rotatable frame, sockets mounted therein, means for rotating said sockets ontheir individual axes in certain positions, globe-holders havirr stems.

frictionally engaging said sockets, a heatingburner ada ted to 006 erate with one of the globes, an a glazing-burner adapted to c0- operate with another.

5. The combination of a rotatable frame, globe-holders each consisting of a recessed block with a stem, sockets carried by said frame adapted to receive said stem, pinions on said sockets, and means for engaging said pinionsin a certain position to frictionally rotate the corresponding lobeholder, and a burner cooperating with t e globe carried by such holder. v

6. The combination of a rotatable frame,

globe-holders each consisting ofa recessed lock with a stem, sockets carried by said.

frame adapted to receive said stem, pinions on saidsockets, means for enga ing said pinions in a certain position to frictionally rotate the globe-holders, a heating-burner and a glazing-burner cooperating with globes carried by said holders, and means for raising or lowering said frame to adjust the position of the globe being glazed.

7. The combination of a tubular standard, a frame rotatably journaled on the standard, means for raising or lowering the frame, gas and air pipes passing upward through the standard, a burner fed thereby and located above the rotatable frame and pointing outwardly, and individual globe-holders rotatably mounted on the frame.

8. The combination of a tubular standard, a collar slidable thereon, a rotatable frame journaled on the standard and resting on said collar, means for raising or lowerin the collar, gas and air pipes passin u War through the standard, a burner fe t ereby and lo .-cated above the rotatable frame and pointin outwardly, individual globe-holders rotataily mounted onthe frame, and means for frictionally rotating said globe-holders when in position to cooperate with said fiameh In testimony whereof I. hereunto affix my signature in the presence oftwo Witnesses.
